STEPS TO REPRODUCE:
1. Navigate to Administration > Objects. Search for the "Team" object. Search for "Booking Status" attribute
2. Set "Default" as "Hard"
3. Create an Idea
4. Allocate a team member to the Idea in the "Team" tab. Notice that its status defaults to "Hard"
5. Approve and Convert this idea to a project (without using templates)
6. Navigate to the newly created project's "Team" tab
Note: This applies to the Classic and Modern 'New From Template'
Expected Results: The resource present in the "Team" tab of the project has Booking Status = "Hard"
Actual Results: The resource present in the "Team" tab of the project has Booking Status = "Soft"
Release: 15.6.1+
This behaviour was reported to Product Engineering via DE50603.
It was determined that this is an intended behaviour of the application. While converting Team Members from an Idea to a Project, the application intentionally marks their Booking Status as Soft. The application is designed to do this.
